2:Square V/F:It is applicable to centrifugal loads such as fan and pump.
10:V/F complete separation:In this mode, the output frequency and output voltage of
the AC drive are independent. The output frequency is determined by the frequency source,
and the output voltage is determined by "Voltage source for V/F separation" (PA.13).It is
applicable to induction heating, inverse power supply and torque motor control.
11 : V/F half separation : In this mode, V and F are proportional and the proportional
relationship can be set in PA.12. The relationship between V and F are also related to the
rated motor voltage and rated motor frequency in Group PA.
Assume that the voltage source input is X (0 to 100%), the relationship between V and F is:
V/F = 2 * X * (Rated motor voltage)/(Rated motor frequency)

Torque boost
Setting Range:0.0%~
30.0%
Model
dependent
To compensate the low frequency torque characteristics of V/F control, you can boost the
output voltage of the AC drive at low frequency by modifying P5.01.
If the torque boost is set to too large, the motor may overheat, and the AC drive may suffer
overcurrent.
